  • Actuator KR20

A compact, high stiffness, and highly accurate actuator with an integrated inner block consisting of an LM block and a ball screw nut.
Also, the housing A/B doubles as a support unit, and the inner block doubles as a table.
It has become possible to significantly reduce design and assembly labor-hours.

[Features]
・ Since it is arranged at a contact angle of 45° so that the load is equal in 4 directions, it can be used in any posture.
・ Since the straight guide section has a 4-row circular arc groove, there is no gap and highly stiff guidance can be obtained.
・ Changes in frictional resistance due to load fluctuations are minimized and follow high accurate feed.
・ The U-shaped cross-sectional outer rail improves stiffness against moments and twists.
